The light source of filament bulbs is mainly provided by primary or secondary batteries or dry batteries and flows through the small and fragile filaments to make them reach a certain high temperature and undergo heat-light energy conversion, only a small part (5% to 10 %) electrical energy is converted into light energy for lighting, and most of the precious electrical energy (90% to 95%) is wasted in the form of heat energy. The filament is relatively fragile and is easily broken by external impact (such as falling on the ground or accidental collision, etc.), and its service life is also very short (usually less than 500-1000 hours), and it is often scrapped due to fracture before it burns out naturally.

The above functions 7-8 are similar to the functions of emergency lights, which can realize emergency lighting when the mains power is cut off or tripped.

In order to simplify the operation of the embodiment of the present utility model, the above functions 3 and 5 can be appropriately canceled as required.

Because all accessories such as the induction receiving coil frame 310 and the induction receiving coil 311 of the semiconductor illuminator 1, rechargeable battery or rechargeable battery pack 38, function control circuit 37, and LED optical components 33-35 have small size, light weight, and low power consumption , no heat dissipation, etc., can be highly integrated and combined, the length of the entire semiconductor illuminator 1 can be controlled within 5 to 15 centimeters, can be fully grasped within a single palm, and is easy to carry and operate.

When the utility model is used as a multi-functional semiconductor illuminator, it can provide high-quality, bright and uniform concentrating parallel light spots with a range of 50m or more. After each full charge of the rechargeable battery or rechargeable battery pack, it can sustain strong light for 3~ 6 hours or more, suitable for military, police, civilian and other widely used. When used as a flashing warning, it has a large luminous area and a wide visual range, and the sustainable flashing warning time is twice or more than continuous lighting, which can meet different warning lighting requirements. To prolong the working time of the semiconductor illuminator of the embodiment of the utility model, it can be easily satisfied by increasing the capacity of the rechargeable battery pack.

The utility model makes full use of the unique technology and process to innovate the function and shape of the multi-functional semiconductor illuminator such as portable lightweight illuminator, warning light and emergency light, etc., and realizes the traditional illuminator or emergency light. Many characteristics and advantages such as explosion-proof, anti-spray, waterproof, dust-proof, vibration-proof, drop-proof, corrosion-proof, high and low temperature resistance, long life, light and beautiful, easy to use, energy saving and environmental protection are difficult to realize. The utility model adopts fully enclosed high-quality engineering plastics or other non-metallic or metal high-grade sealed outer shells, and uses ultrasonic sealing technology or other welding techniques to weld the outer shell parts tightly and precisely into one body, and integrates different internal optics, electricity, machinery, etc. The system is a non-detachable organic fastening structure. At the same time, the non-electric contact tact switch kit placed outside the sealed outer shell is used to control the internal electronic devices to meet the requirements of explosion-proof, anti-spray, waterproof, anti-vibration, anti-corrosion, high and low temperature resistance and Opto-mechanical performance indicators and safety standards for preventing electric shock or fire.

The utility model adopts a reflective and transmissive converging optical system. Since the light radiated by a single LED light source is divergent, the light spot effect is poor, and a complete and uniform parallel beam cannot be formed, so it is not suitable for direct use on a portable illuminator. Some illuminators use LED arrays to expand the emitting area of the light source to directly form a beam of light, but the uniformity of the beam is poor and will vary with the number of LEDs and the color tone quality of each LED. The utility model makes full use of the advantages of the precise reflection and transmission converging dual optical system, and can accurately design the focal length, curvature, surface diameter, thickness, surface diameter, divergence angle, spacing and other parameters of the optical reflector and the transmission lens, and the LED The divergent light of the point light source converges into parallel light or quasi-parallel light to realize a complete and uniform single-spot high-intensity beam based on secondary optical optimization of multiple ultra-high brightness LED arrays or a single high-power LED light source.

On the basis of realizing the above multi-functions, the utility model can also set a voltage output plug on a suitable position on the semiconductor illuminator, and add a special conversion joint to realize mobile phones, personal digital assistants, walkie-talkies, digital cameras/video cameras, shaving Knives, high-fidelity radios, flashlights and MP3/MP4 and other electronic and information terminal appliances for emergency charging services. A positioning groove or hole can also be added to the side, body part or bottom of the semiconductor illuminator according to the embodiment of the utility model, and a miniature compass can be embedded in it to increase the guide function.
